This invention relates to improvements in. a road sanding device for use with automobiles and the like. Its primary object being to devise and construct a sanding mechanism having means to hold or release the sand in a container, said means being self-cleaning whereby to prevent sand interfering with the action of the same.

A further object of the device is to use brushes as closure means in conjunction with the sand container and wherein the said brushes are slidable in tubular structures to cover or uncover the sand exit aperture of the said container.

Another object of the invention is to provide means to actuate the said sanding device by means of a foot pedal in the body of the car and to provide heating means when necessary to keep the sand dry and in condition to run freely when released from the container.

A still further object of the invention is to provide a means to actuate the said sanding device by means of an operating device in the body of. the vehicle and a means to provide a closing feature to act independently of the front or rear wheels.

With these and other objects in view that may appear while the description proceeds the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming part of this application and in which:

Figure 1 is a side elevation of my invention shown in conjunction with an automobile part of which is shown in dotted lines.

Fig. 9 is a detail of the modification arranged for double Wheeled vehicles as seen from underneath.

Fig. 10 is a further detail of the brush showing removable or replaceable brushes.

Fig. 11 is a further detail of the brush.

Fig. 12 is a view showing the invention applied to a street car or train wheels. 5

Referring more in detail to the drawings wherein similar reference characters designate corresponding parts throughout the several views it will be seen the invention comprises sand containers [0 arranged in conjunction with the front 10 fenders H, and rear fenders l2 of an automobile.

A filler cap 13 is provided in a convenient position for pouring sand into the containers.

An exit aperture M is positioned in the bottom of each container and a tubular structure I5 is 15 constructed adjacent thereto. Within the said structure is are circular brush members l6 mounted on a centrally disposed rod I! and movable laterally within the said structure. In alignment with the apertures Mare exit troughs I8 having a plurality of holes IS in the bottom thereof through which the sand will fall as it passes from the aperture M to the trough l8 to be spread on the roadway thereby. When in the position shown in Fig. 4 the brushes 5 permit sand to run from the aperture Hi to the trough l8 but prevent same from running laterally along the tube l5. In the position shown in Fig. 5, one of the brushes closes the exit aperture and thereby prevents sand from escaping. As the brushes and the tube are of circular crosssection the wear of the brushes if any, will be equally distributed around the circumference of the same, and any movement laterally as in the course of being actuated to liberate sand the brushes will serve to clean any surplus sand from the tube.

A foot pedal 20 is pivotally mounted between the supporting brackets 20' by means of a pivot pin 2i and the lower end of the pedal has an elongated slot 22 through which extends the cross arm 2| extending between the brush rods l1 and connected thereto by suitable connections 22. Upon actuation of the pedal by the foot the cross arm 2| is moved to reciprocate the brush rods l'l.

Provision is made for the addition of an electric heating element 23 which may be included within an insulating casing in the sand containers and a flexible cord 24 is provided to conmeet the same with a source of current which may be the car battery or an outside source when the car is in the garage.

In the alternate structure shown in Fig. 8, the brushes are placed at right angles to the front wheels and parallel to the rear wheels. Fig. 9 shows an enlarged detail view of the right angle structure as arranged for double wheeled vehicles. This structure includes flexible cables 25 enclosed in conduits 26. Said conduits are attached to the brush tubes l at 21 in a suitable and secure manner and the brushes are attached to the cables 25 within the tubes E5 to be actuated laterally by the movement of the same. Suitable spring means as 28 are provided to retract the mechanism and'hold the brushes normally in the closed position.

. In Figs. 10 and 11 a demountable type of brush is shown. The same are secured on the rod H by rollers 29 having set screws 30 threadable therein and by means of which they are secured in position.

In Fig. 12 the device is shown in conjunction with a pair of flanged wheels 3! as used on street cars, railway locomotives, cars or the like to which the invention is adaptable. With this typeof vehicle now using sanding devices of various kinds it is believed the brush closure means will be advantageous over the present metal closure means wherein there is considerable wear and more or less inefficient operation due to the sand grains getting between the co-acting metal elements and. preventing complete closure or: the same thereby permitting a certain amount of loss of the sand.

It will be seen from the drawings that the sand when delivered from the container to the trough will be partially distributed directly below or in the track of the wheels while the trough will also direct someof the sand to the side of the track of the wheels. In this manner sand will be directed on a slippery road or other surface or in a rut or on the side of rut to enable a car to get out of the same and also toaid in giving a complete traction when turning corners or rounding a curve.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it is understood that minor changes in the details of construction, com-' bination and arrangement of co-operating parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

I claim:

1. In a sanding device as described comprising a hopper associated with the fenders of a vehicle having a discharge opening in the bottom thereof, a tubular valve body connected to the lower end of said hopper across the discharge opening and communicating therewith, a discharge spout extending from said valve body, a brush member mounted to reciprocate in said valve body, and means for reciprocating the brush member to cover and uncover the discharge opening of said hopper.

2. In a sanding device as described comprising a hopper associated with the fenders of a vehicle having a discharge opening in the bottom thereof, a tubular valve body connected to the lower end of said hopper extending transversely of the discharge opening and communicating therewith, a discharge spout extending from said valve body, a valve rod adapted to reciprocate in said valve body, and a pair of circular brush members mounted on said valve rod in spaced relation adapted to cover and uncover the discharge opening of said hopper upon reciprocation of said'valve rod. 7 V

3. In a sanding device as described comprising a hopper associated with the fenders of a vehicle having a discharge opening in the bottomthereof, a tubular valve body connected to the lower end of said hopper extending transversely of the. discharge opening and communicating therewith,

a discharge spout extending laterally from the valve body having a series of spaced apertures in its bottom wall, a brush member slidably mounted in said valve body, and a rod for reciprocating said brush member to cover and uncover said discharge opening and the inner end of said spout.
